Answer:
The GCF of 45 and 18 is 9
9(5+2)
(P.S. the sum of all of the number is 63)
Plug in point values into the distance formula
*square root of* (-9+4)^2 + (0+8)^2
d≈ 9.4

Answer:
400 meters
Step-by-step explanation:
First, divide 3,200 by 24 to find the rate, which is 133.3 (repeated).
Now, multiply 133.3 by 3, which is your answer! 133.3*3=399.9. 399.9 is extremely close to 400, so we can just round it to that.
Hope this helps you out and have a wonderful day (✿◡w◡)
